An enzyme in the bacterium that causes potato scab could help create new, environmentally-benign biocatalysts with the potential to cut use of the highly corrosive chemical nitric acid. Chemists at ...

IT was known fifty years ago that hydroxy byproducts arise in small quantities in the nitration of benzene and toluene, and their significance was discussed by Armstrong and Rossiter in 1891. Since ...

IN order to check the constitution of preparations of the three different tritium toluenes carrying radiochemical amounts of tritium in the aromatic nucleus, samples were transformed into ...

An enzyme in the bacterium that causes potato scab could help create new, environmentally-benign biocatalysts with the potential to cut use of the highly corrosive chemical nitric acid. An enzyme in ...

Chemists have yet another use for fluorine, as a through-space activator for electrophilic aromatic substitutions. Thomas Lectka and coworkers at Johns Hopkins University used a Diels-Alder reaction ...

Air, pressure, heat, corrosive agents, and other factors encountered by a lubricant during use can cause chemical changes in the oil. Changes in the oil chemistry can have a negative impact on the ...
